This study examines the association between dental calculus and hypertension (HTN) in young adults. The results show that dental calculus is associated with combined HTN, but not with isolated systolic HTN and isolated diastolic HTN.
Background Poor oral health evaluated by presence of dental calculus has been associated with hypertension (HTN) among middle- and old-aged adults. However, it is unclear for the association of HTN phenotypes with dental calculus in young adults. Methods This study examined the association between dental calculus and HTN in 5,345 military personnel, aged 19-45 years, without antihypertensive medications therapy in Taiwan from 2018 to 2021. Dental calculus was defined as presence of supragingival calculus in any teeth, except impacted teeth, and third molar. Combined HTN (CHTN) was diagnosed as systolic blood pressure (SBP) >= 130 mm Hg and diastolic blood pressure (DBP) >= 80 mm Hg. Isolated systolic and diastolic HTN were, respectively, defined as SBP >= 130 mm Hg only (ISHTN) and DBP >= 80 mm Hg only (IDHTN). Multiple logistic regression with adjustments for sex, age, toxic substance use, anthropometrics, lipid profiles, fasting glucose, and blood leukocyte counts were used to determine the association between dental calculus and HTN phenotypes in young adults. Results The prevalence of those with dental calculus, CHTN, ISHTN, and IDHTN was 20.8%, 10.8%, 10.2%, and 7.0%, respectively. The dental calculus was associated a greater possibility with CHTN [odds ratio (OR) and 95% confidence interval: 1.60 (1.31-1.95)]. However, the associations of dental calculus with ISHTN and IDHTN were null [OR: 1.05 (0.81-1.27) and 1.12 (0.86-1.46), respectively]. Conclusions Our findings suggest that among young adults, poor oral health manifested by presence of dental calculus was associated with a greater possibility of CHTN, while not for ISHTN and IDHTN.
